Hypertech Max Energy Programmer Reviews

I wanted something that I could program myself instead of sending of my PMC to someone eles to program. I was able to change my tire size to compensate for the 33in tire I installed, also was able to change my shift point and shift firmness as well. It also came with two performance setting, an 87 and a 91 octane. I used the 87 octane in my 3.7 liter and I got a boost in performance and mileage as well. Which made me very happy.

Superchips Flashpaq Tuner Reviews

I had purchased other brands before for different cars and they were not that great so I was skeptical. I am very happy with the boost in performance this gave to my H3 5.3L V8. It has a much more responsive feel with firmer shifts which I like. So far I've only had time for the 87 Octance Performance Tune but I want to give it some testing time. Not only is performance better but it added 1/2 MPG to my average at the same time. Can't wait to try the other features.
